The relationship between yield of milk solids of dairy cows and response to change in plane of nutrition

Abstract: SUMMARYA study is reported of the effect of initial potential for milk production of individual cows on the change in milk output consequent upon a change in amount of feed allowed per day. In this study equal initial rations and equal changes in ration were imposed on all cows. The main conclusion was that the greater the initial yield of milk, of milk fat, of solids-not-fat (SNF) or the SNF content of the milk of a cow the greater was the effect of a change in feed allowance on that attribute. It is argued t… Show more

“…In the experiment by Kirkland and Gordon (2001b), the initial milk yields of the cows were 34.3 and 18.3 kg/cow per day at 158 and 414 DIM, whereas in our experiment, milk yields were only 21 kg/cow per day at 110 DIM and they declined at subsequent stages of lactation. The greater partitioning to milk energy observed by Kirkland and Gordon (2001a), particularly in early lactation (77 DIM), may be explained by the higher initial milk yield in their experiment (40.7 kg/ cow per day) because the initial milk yield of the cows is an important factor in explaining higher responses in milk to changes in feeding levels (Broster et al, 1981;Grainger, 1990). It is also possible that potential differences in the genetic merit of the cows used in the 2 studies was a factor contributing to the differences in energy partitioning to milk.…”

“…In conclusion, it has been appreciated for a long time that a cow's performance responds to change in plane of nutrition but also that the response is subject to various factors (Agricultural Research Council, 1965, 1980Broster et al 1981;Johnson, 1983;Gordon, 1984). The present trial calibrates some of these factors including stage of lactation and parity.…”

“…On the other hand, Smith et al (1978), Moseley, Coppock & Lake (1976) and Akinyele & Spahr (1975) have shown that switching cows from a high to a medium energy diet has affected the milk production. Broster et al (1981) and Moseley et al (1976) suggested that the negative effect of the diet change is small, because of residual effects carried on from early to later lactation.…”
